Your CEO calls you in to her office and tells you she is frustrated with the inconsistent results the company’s current recruitment and selection process is having in yielding excellent candidates. She knows you are working on your MBA at SFA and asks you for some ideas on things the organization could do to improve the situation. Provide at least three items you learned about from the articles and class lectures/discussions. Be sure to go beyond just listing three things and explain how each would help improve the outcome.

A scientific study conducted in 2017 wanted to determine if a person drinking soda attracts more flies than a person drinking water.  The study looked at 62 adult volunteers who were randomly assigned to consume either soda or water. Their attractiveness to flies was measured by counting how many flies approached each person in a one-hour period.  Of the 31 adults assigned to the soda group, they found that the average number of flies was 132.  With the 31 adults assigned to the water group, they found the average number of flies was 130. The correct null and alternative hypotheses for this situation would be: Ho: Ha: Assuming the relevant p-value for this test was 0.352, complete the conclusion below: We the null hypothesis.  We convincing evidence that there is a difference in the mean number of flies that were attracted when comparing soda and water drinkers.

Two researchers completed the same study when considering the same hypothesis test. Researcher A obtained a p-value of 0.04. Researcher B obtained a p-value of 0.03. Based on this information, the p-value from researcher provides stronger evidence against the null and in favor of the alternative.  Use a significance level of 0.05. Researcher A should the null hypothesis. Researcher B should the null hypothesis.
